Description

Technical Field

[0001] This invention relates to the field of track slab production technology, and in particular to a steel cage clamping mechanism, system, and track slab casting construction method. Background Technology

[0002] With the rapid development of high-speed railway construction in my country, track slabs, as a core component of ballastless track structures, have seen increasingly mature and sophisticated manufacturing technologies. During the track slab manufacturing process, the reinforcing cage, as a crucial load-bearing structure, requires precise transfer and installation procedures.

[0003] Currently, in track slab manufacturing technology, the transfer and installation of reinforcing cages are mainly achieved through manually driven hoisting mechanisms. When using hoisting equipment to lift the reinforcing cages, lifting lugs are directly connected to the cages to achieve the lifting and transfer function. Although this method can achieve the function of transferring the reinforcing cages, in actual transfer, the complexity of installing the lifting lugs results in a limited number of lugs. This makes the reinforcing cages prone to tilting during the final hoisting process, leading to defects such as displacement or damage to the stirrups and other structures on the cages, affecting the forming quality and overall strength of the track slab. Summary of the Invention

[0004] The main objective of this invention is to propose a rebar cage clamping mechanism, system, and track slab casting construction method. This invention aims to solve the technical problem that, in the actual transfer process of existing technologies, the complex installation of lifting lugs results in a limited number of lifting lugs, which in turn leads to the rebar cage tilting during the final hoisting process. This causes displacement or damage to the stirrups and other structures on the rebar cage, thus affecting the forming quality and overall strength of the track slab.

[0005] To achieve the above objectives, in a first aspect, the present invention provides a steel cage clamping mechanism, comprising: A frame, wherein a plurality of spaced-apart hoisting positions are formed at the top of the frame, and a plurality of spaced-apart installation positions are formed at the bottom of the frame; and, Multiple clamping components are provided, with the number of clamping components matching the number of installation positions and installed in a one-to-one correspondence. Each clamping component includes a mounting plate and two clamping plates. The mounting plate is installed at the installation position, and its bottom has two horizontally spaced pin holes. The two clamping plates are arranged side by side and are riveted to the two pin holes one-to-one by pins. Both clamping plates can rotate around their corresponding pins. The opposite sides of the two clamping plates are recessed to form receiving grooves, and the bottom of one of the receiving grooves has an anti-detachment protrusion. The receiving grooves on the two clamping plates are arranged opposite each other to form receiving holes for accommodating the main reinforcement bars of the reinforcing cage. The end of each clamping plate away from the mounting plate is formed with a pointed tip, and the end of each clamping plate near the mounting plate has two interlocking arc-shaped toothed rings. All the corresponding two clamping plates on the mounting plate can be inserted into the reinforcing cage and clamped onto the main reinforcement bars of the reinforcing cage to clamp the reinforcing cage.

[0006] In one embodiment, the clamping component further includes an elastic reset member connected between the two clamping plates, the elastic reset member causing the two clamping plates to clamp the main rib.

[0007] In one embodiment, one of the clamping plates is fixed to the corresponding pin, and the clamping component further includes a drive motor mounted on the mounting plate. The output shaft of the drive motor is connected to the pin fixed to the corresponding clamping plate to drive the output shaft to rotate and open the corresponding clamping plate and lower the steel cage.

[0008] In one embodiment, the elastic reset member is an omega spring, the spring body of which is fixed to the side of the two clamping plates near the mounting plate by two screws, and the two torsion arms of the omega spring are respectively connected to the side of the two clamping plates away from the mounting plate.

[0009] In one embodiment, the receiving holes have at least two, and the at least two receiving holes are spaced apart along the extension direction of the clamping plate.

[0010] In one embodiment, a snap-fit ​​protrusion is formed at each of the said mounting positions; The mounting plate includes: The plate body has bolt holes at both ends, and also has pin holes spaced apart from the bolt holes; and, Two snap-fit ​​blocks are disposed opposite each other at both ends of the plate body, and each snap-fit ​​block is connected to the plate body through a bolt hole provided at the same end, so as to form a snap-fit ​​groove with the plate body, and the snap-fit ​​groove can snap into the snap-fit ​​protrusion.

[0011] In one embodiment, both the snap-fit ​​protrusion and the plate body have pin holes, and the clamping component further includes a pin that can be inserted into the pin hole to fix the plate body in the mounting position.

[0012] In one embodiment, a lifting lug is also provided at the hoisting position.

[0013] Based on the same technical concept, in a second aspect, the present invention also proposes a rebar cage clamping system, comprising: Walking mechanism; and, The first aspect describes a rebar cage clamping mechanism, wherein the traveling mechanism is connected to the hoisting position on the rebar cage clamping mechanism.

[0014] Based on the same technical concept, in a third aspect, the present invention also proposes a method for casting track slabs, comprising the following steps: Install the formwork structure in the pre-designated construction area to obtain the pre-designated pouring position; The steel cage is hoisted and placed at the preset pouring position using the steel cage clamping system described in the second aspect. The track slab is manufactured by pouring concrete at the preset pouring station.

[0015] The technical solution of this invention, through the setting of a frame and multiple clamping components, provides multiple spaced-apart hoisting positions at the top of the frame and multiple spaced-apart installation positions at the bottom of the frame. The number of clamping components matches the number of installation positions and they are installed one-to-one. Each clamping component includes a mounting plate and two clamping plates. The mounting plate is installed at the installation position, and its bottom has two horizontally spaced pin holes. The two clamping plates are arranged side by side and are each riveted to one pin hole by pins. Both clamping plates can rotate around their corresponding pins. The opposite sides of the two clamping plates are recessed to form receiving grooves, and the bottom of one of the receiving grooves has an anti-detachment protrusion. The receiving grooves on the two clamping plates are arranged opposite each other to form receiving holes for receiving the main reinforcement bars of the steel cage, and the end of each clamping plate away from the mounting plate is formed with a pointed tip. Two clamping plates have interlocking arc-shaped toothed rings at their ends near the mounting plate. The two corresponding clamps on all mounting plates can be simultaneously inserted into the reinforcing cage and clamped onto the main reinforcing bars of the reinforcing cage to clamp the reinforcing cage. This allows the invention to utilize the anti-detachment protrusion in the receiving groove of one of the clamping plates to receive the main reinforcing bars and prevent them from falling out of the receiving groove. This enables the invention to clamp and transfer the reinforcing cage. Furthermore, multiple clamping components are provided, and each clamping component can clamp the main reinforcing bars on the reinforcing cage. This allows the invention to simultaneously clamp multiple positions on multiple main reinforcing bars on the reinforcing cage during specific use. Ultimately, this reduces the risk of damage to the stirrups on the reinforcing cage due to tilting or displacement during the transfer process, thus ensuring the forming quality of the track slab.

[0023] This invention proposes a steel cage clamping mechanism, system, and track slab casting construction method.

[0024] Please see Figures 1 to 7 For ease of understanding, this steel cage clamping mechanism 20 includes: The frame 100 has multiple spaced-apart hoisting positions at its top and multiple spaced-apart installation positions at its bottom; and... Multiple clamping components 200 are provided, with the number of clamping components 200 matching the number of installation positions and installed one-to-one. Each clamping component 200 includes a mounting plate 210 and two clamping plates 220. The mounting plate 210 is installed at the installation position, and its bottom has two horizontally spaced pin holes. The two clamping plates 220 are arranged side by side and are riveted to the two pin holes one-to-one by pins. Both clamping plates 220 can rotate around their corresponding pins. The opposite sides of the two clamping plates 220 are recessed to form receiving grooves. Furthermore, one of the receiving slots has an anti-detachment protrusion 240 at its bottom, and the receiving slots on the two clamping plates 220 are arranged opposite each other to form receiving holes 221 for receiving the main reinforcement bars of the steel cage. Each clamping plate 220 has a pointed tip 222 at the end away from the mounting plate 210, and each of the two clamping plates 220 has two interlocking arc-shaped toothed rings 223 at the end near the mounting plate 210. The two clamping plates 220 on all the mounting plates 210 can be inserted into the steel cage together and clamped onto the main reinforcement bars of the steel cage to clamp the steel cage.

[0025] Specifically, the frame 100 has a rectangular structure, with four hoisting positions spaced along its length at the top and multiple installation positions corresponding to the bottom. Each clamping component 200 is installed at one of the installation positions, enabling simultaneous clamping of the reinforcing cage at multiple points.

[0026] Specifically, each clamping component 200 includes a mounting plate 210 and two clamping plates 220. The mounting plate 210 is fixedly mounted to the corresponding mounting position by bolts. The bottom of the mounting plate 210 has two pin holes spaced horizontally, with the spacing between the two pin holes preferably being 100mm. The two clamping plates 220 are arranged side by side, and each clamping plate 220 is riveted to one of the pin holes by pins. The two clamping plates 220 can rotate freely around their respective pins.

[0027] The two clamping plates 220 are recessed on their opposite sides to form receiving grooves, and one of the receiving grooves has an anti-detachment protrusion 240 at the bottom. The receiving grooves on the two clamping plates 220 are arranged opposite each other to form receiving holes 221 for receiving the main bars of the steel cage.

[0028] In use, the rebar cage clamping mechanism 20 of this application is connected to multiple hoisting positions on the top of the frame 100 via a lifting device, driving multiple clamping components 200 at the bottom of the frame 100 to move simultaneously. When it is necessary to clamp the rebar cage, the two clamping plates 220 of each clamping component 200 rotate downwards and open under their own weight, with the pointed ends 222 partially inserted into the rebar cage. After the clamping plates 220 are inserted into the rebar cage, they rotate inwards under the action of the main reinforcement bars, and the receiving grooves on the two clamping plates 220 form receiving holes 221 and clamp the main reinforcement bars. At the same time, the arc-shaped toothed rings 223 mesh with each other to lock the relative position of the clamping plates 220, preventing the clamping plates 220 from loosening. The anti-detachment protrusions 240 at the bottom of the receiving grooves further increase the friction with the main reinforcement bars, improving the clamping reliability.

[0029] The clamping plate 220 adopts a pin hinge method, which is simple and reliable in structure. The tip 222 is designed for easy insertion, and the arc-shaped toothed ring 223 can lock the clamping position. The anti-dislodgement protrusion 240 increases the friction. The multiple structures ensure the stability and reliability of clamping, effectively solving the technical problem in the prior art that the steel cage is prone to tilting during the transfer process, resulting in the displacement or damage of the stirrups.

[0030] It can be further clarified that, in this embodiment, in specific implementation, by setting one of the receiving grooves to have an anti-detachment protrusion 240 structure in the groove opening direction, in specific use, the main reinforcement of the steel cage can be prevented from falling out of the receiving groove by the anti-detachment protrusion 240, thereby enabling the present invention to smoothly carry out the hoisting, transfer and installation of the steel cage.

[0031] Specifically, by setting up a frame 100 and multiple clamping components 200, in use, the top of the frame 100 forms multiple spaced hoisting positions, and the bottom of the frame 100 forms multiple spaced installation positions. The number of clamping components 200 is consistent with the number of installation positions and they are installed one-to-one. Each clamping component 200 includes a mounting plate 210 and two clamping plates 220. The mounting plate 210 is installed at the installation position. The bottom of the mounting plate 210 is provided with two horizontally spaced pin holes. The two clamping plates 220 are arranged side by side and are each riveted to one pin hole by pins. Both clamping plates 220 can rotate around the corresponding pins. The sides of the two clamping plates 220 that are arranged opposite each other are recessed to form receiving grooves, and the bottom of one of the receiving grooves has an anti-detachment protrusion 240. The receiving grooves on the two clamping plates 220 are arranged opposite each other to form receiving holes 221 for receiving the main reinforcement of the steel cage, and each clamping plate 220 is far from each other. One end of each mounting plate 210 is formed with a pointed tip 222, and the two clamping plates 220 near the mounting plate 210 are formed with interlocking arc-shaped toothed rings 223. The two clamps on all mounting plates 210 can be inserted into the steel cage at the same time and clamped onto the main reinforcement bars of the steel cage to clamp the steel cage. This allows the present invention to use the anti-detachment protrusion 240 in the receiving groove on one of the clamping plates 220 to receive the main reinforcement bars and prevent them from falling out of the receiving groove. This allows the present invention to clamp and transfer the steel cage. On this basis, multiple clamping components are set, and each clamping component can clamp the main reinforcement bars on the steel cage. This allows the present invention to clamp multiple positions on multiple main reinforcement bars on the steel cage at the same time during specific use. This reduces the risk of damage to the stirrups on the steel cage due to tilting or displacement during the transfer of the steel cage, and ultimately ensures the forming quality of the track slab.

[0032] In one embodiment, the clamping component 200 further includes an elastic reset member 230, which is connected between two clamping plates 220 and causes the two clamping plates 220 to clamp the main rib.

[0033] Specifically, the elastic reset member 230 is an omega spring, which is sleeved on one of the pins. The two torsion arms of the omega spring abut against the two clamping plates 220 respectively, and the torsion of the omega spring causes the two clamping plates 220 to clamp the main rib.

[0034] By adding an elastic reset member 230 between the clamping plates 220, the elastic force of the elastic reset member 230 keeps the two clamping plates 220 always clamping inward. This, combined with the anti-detachment protrusion 240 at the bottom of the receiving groove and the arc-shaped toothed ring 223, further improves the reliability of the clamping component in holding the main reinforcing bar, ensuring that the reinforcing cage will not loosen or fall off during transfer. At the same time, the elastic reset member 230 has a simple structure and is easy to install, without increasing the overall complexity of the clamping component, maintaining the simplicity and practicality of the clamping structure.

[0035] In one embodiment, one of the clamping plates 220 is fixed with a corresponding pin, and the clamping component 200 further includes a drive motor 224, which is mounted on a mounting plate. The output shaft of the drive motor 224 is connected to the pin fixed to the corresponding clamping plate 220, so as to drive the output shaft to rotate and open the corresponding clamping plate 220 and lower the steel cage.

[0036] Specifically, one of the clamping plates 220 is interference-fitted with a corresponding pin to form an output shaft. The output shaft of the drive motor 224 is connected to this output shaft to realize the rotation control of the corresponding clamping plate 220. The drive motor 224 receives instructions through the electronic control system and drives the corresponding clamping plate 220 to rotate open or close as needed, thereby realizing the automatic clamping and lowering of the rebar cage.

[0037] The interference fit between the clamping plate 220 and the corresponding pin ensures a sufficiently tight connection between them, effectively transmitting the rotational power generated by the drive motor 224 to the clamping plate 220. This allows for precise control of the rotation angle of the clamping plate 220, thereby achieving accurate clamping and placement of the rebar cage. The selection of the drive motor 224 can be determined based on the size of the clamping plate 220 and the expected load to ensure sufficient torque to control the movement of the clamping plate 220.

[0038] In another embodiment, the drive motor 224 may be equipped with a sensor, such as an angle sensor, to feed back the actual position information of the clamping plate 220 to the control system. In this way, the control system can adjust the operating state of the drive motor 224 according to the position of the clamping plate 220, ensuring that the clamping plate 220 clamps or releases the rebar cage at the correct angle, further improving the accuracy and reliability of the operation.

[0039] By adding a drive motor 224 and a related control system, the rebar cage clamping mechanism 20 of this embodiment can achieve automated clamping and lowering operations, reducing the need for manual operation and improving work efficiency and safety. At the same time, the interference fit design ensures a stable connection between the clamping plate 220 and the output shaft, enabling the movement of the drive motor 224 to be efficiently and accurately transmitted to the clamping plate 220, ensuring the reliability and stability of the operation.

[0040] In one embodiment, the elastic reset member 230 is an omega spring. The spring body of the omega spring is fixed to the side of the two clamping plates 220 near the mounting plate 210 by two screws, and the two torsion arms of the omega spring are respectively connected to the side of the two clamping plates 220 away from the mounting plate 210.

[0041] Specifically, the omega spring has a fixing hole in its center. A screw passes through this fixing hole and is simultaneously threaded into the connection point of the two clamping plates 220, thereby firmly fixing the omega spring between the two clamping plates 220. The two torsion arms of the omega spring extend to the inner sides of the two clamping plates 220 and abut against the inner walls of the clamping plates 220.

[0042] Based on this, the Omega spring is installed in the middle area of ​​the two clamping plates 220, and the screw is installed perpendicular to the plane of motion of the clamping plates 220. When the clamping plates 220 are in the open state to clamp the rebar cage, the two torsion arms of the Omega spring are driven by the opening action of the clamping plates 220 to generate torsional deformation, and torsional elastic potential energy is accumulated inside the Omega spring.

[0043] When the clamping plate 220 is inserted into the reinforcing cage and contacts the main reinforcement bar, the omega spring releases its accumulated torsional elastic potential energy. This energy, through the torsion arm, applies opposing torsional torques to the two clamping plates 220, causing them to rotate inward and clamp the main reinforcement bar. The torsional torque of the omega spring matches the rotation direction of the clamping plates 220 around the pin, ensuring that the clamping plates 220 can stably clamp the main reinforcement bar under the action of the omega spring.

[0044] By employing an omega spring as the elastic reset element 230 and simultaneously fixing it to both clamping plates 220 with screws, a reliable connection between the elastic reset element 230 and the clamping plates 220 is achieved. Compared to a tension spring, the omega spring has a more compact structure, occupies less space, and its torsional torque acts more directly and effectively, providing a continuous and stable clamping force to the clamping plates 220. The screw fixing method facilitates installation and maintenance; when the omega spring needs to be replaced, only the screws need to be removed to complete the replacement, improving the maintenance convenience of the clamping mechanism.

[0045] In one embodiment, the receiving holes 221 have at least two, and the at least two receiving holes 221 are spaced apart along the extension direction of the clamping plate 220.

[0046] Specifically, one of the receiving grooves has an anti-detachment protrusion 240 at the bottom, which is located in the middle of the receiving groove. When the clamping plate 220 clamps the main rib, the anti-detachment protrusion 240 mechanically engages with the surface of the main rib, increasing frictional resistance and preventing the main rib from sliding or detaching within the receiving hole 221.

[0047] By providing multiple receiving holes 221 spaced apart along the extension direction of the clamping plate 220, the clamping mechanism of this application can simultaneously clamp multiple main bars of the reinforcing cage. Compared with single-point clamping, multi-point clamping can effectively distribute the clamping load, reduce the stress concentration on a single main bar, and avoid deformation or damage to the main bar. At the same time, the distribution of multiple receiving holes 221 increases the stability of clamping, prevents the reinforcing cage from rotating or swaying during transfer, and ensures that the reinforcing cage maintains the correct posture.

[0048] In one embodiment, a snap-fit ​​protrusion 110 is formed at each mounting position; Mounting plate 210 includes: Plate 225, with bolt holes formed at both ends, and also with dowel holes spaced apart from the bolt holes; and, Two snap-fit ​​blocks 226 are disposed opposite to each other at both ends of the plate 225, and each snap-fit ​​block 226 is connected to the plate 225 through a bolt hole provided at the same end, so as to form a snap-fit ​​groove with the plate 225, and the snap-fit ​​groove can snap into the snap-fit ​​protrusion 110.

[0049] Specifically, two snap-fit ​​blocks 226 are respectively disposed at the left and right ends of the plate 225, and each snap-fit ​​block 226 is connected and fixed to the bolt holes on the corresponding side by two bolts. The inner surface of the snap-fit ​​block 226 forms an L-shaped slot with the end of the plate 225, which can engage with the head of the snap-fit ​​protrusion 110. When the mounting plate 210 is installed on the mounting plate, the head of the snap-fit ​​protrusion 110 is inserted into the slot, and the reliable connection between the mounting plate 210 and the mounting plate is achieved through the engagement of the neck of the snap-fit ​​protrusion 110 with the opening of the slot. This allows the clamping component 200 to be stably installed on the mounting plate, while facilitating the disassembly and maintenance of the clamping component 200. The bolt connection between the snap-fit ​​block 226 and the plate 225 allows the size of the slot to be adjusted according to different specifications of the snap-fit ​​protrusion 110, improving the applicability of the mounting plate 210.

[0050] Through the engagement of the snap-fit ​​protrusion 110 and the slot, a reliable mechanical connection is formed between the mounting plate 210 and the mounting plate, which can withstand various loads generated by the clamping component 200 during the clamping and transfer of the reinforcing cage. Compared with the traditional bolt connection, the snap-fit ​​structure has the advantages of quick installation and convenient disassembly. At the same time, the tightness of the snap-fit ​​ensures the stability of the connection and avoids the positional displacement or detachment of the clamping component 200 due to loosening of the connection.

[0051] In one embodiment, both the snap-fit ​​protrusion 110 and the plate 225 have pin holes, and the clamping component 200 also includes a pin 227 that can be inserted into the pin hole to fix the plate 225 in the installation position.

[0052] Specifically, the mounting direction of the pin 227 is perpendicular to the axis of the snap-fit ​​protrusion 110. This cross-fit structure effectively prevents the plate 225 from axially displacing relative to the snap-fit ​​protrusion 110. At the same time, the pin 227 also restricts the rotation of the plate 225 around the snap-fit ​​protrusion 110, forming a double constraint to ensure a stable and reliable connection between the plate 225 and the mounting plate.

[0053] In practical applications, the installation and removal of the pin 227 are simple and quick, requiring no special tools; it can be done simply by hand. When maintenance or replacement of the clamping component 200 is needed, the plate 225 can be easily removed from the mounting plate simply by pulling out the pin 227. This quick-release feature greatly improves the maintenance efficiency of the clamping mechanism.

[0054] In one embodiment, a lifting lug 120 is also provided at the hoisting position.

[0055] Specifically, the number of lifting lugs 120 corresponds one-to-one with the lifting positions, with a total of four lifting lugs 120 located at the four corners of the mounting plate. The arrangement of the four lifting lugs 120 has been mechanically calculated to ensure that the force is evenly distributed during the lifting process, avoiding tilting or swaying of the clamping mechanism due to uneven weight distribution.

[0056] By installing lifting lugs 120 at the lifting position, the clamping mechanism can be well integrated with existing lifting equipment, facilitating overall lifting and movement. Simultaneously, the lifting lugs 120 also provide fixing points for the clamping mechanism, allowing it to be secured in a designated position when needed, preventing displacement.

[0057] Based on the same technical concept, in a second aspect, the present invention also proposes a rebar cage clamping system, comprising: Walking mechanism 10; and, The first aspect is the steel cage clamping mechanism 20, and the traveling mechanism 10 is connected to the hoisting position on the steel cage clamping mechanism.

[0058] Specifically, when a rebar cage clamping operation is required, the operator uses a remote control to move the traveling mechanism 10 to the vicinity of the rebar cage, and then activates the clamping component 200 on the clamping mechanism to clamp the rebar cage. After clamping is completed, the traveling mechanism 10 carries the entire rebar cage clamping mechanism and the rebar cage to the designated location, completing the rebar cage transfer operation.

[0059] By combining the walking mechanism 10 with the rebar cage clamping mechanism, the present invention realizes the integrated operation of rebar cage clamping and transportation, effectively solving the technical problem that additional transportation equipment is required after the rebar cage is clamped in the prior art. By integrating the clamping function and the moving function into the same system, the work efficiency is improved, equipment investment is reduced, construction costs are reduced, and the continuity and safety of the rebar cage transfer process are ensured at the same time.

[0060] Based on the same technical concept, in a third aspect, the present invention also proposes a method for casting track slabs, comprising the following steps: S100. Install the formwork structure in the pre-designed construction area to obtain the pre-designated pouring position; Specifically, in this embodiment, a flat surface is first selected at the construction site as the pre-designated construction area. A formwork structure is then installed within this area. The formwork structure includes a bottom formwork, side formwork, and end formwork. The bottom formwork is made of a steel base plate with a polished surface. The side and end formwork are made of channel steel and sealed with sealing strips.

[0061] S200. The steel cage is hoisted and placed at the preset pouring position using the steel cage clamping system of the second aspect.

[0062] Specifically, in this step, a traveling mechanism is used to move the rebar cage clamping mechanism to the rebar cage stacking area. The clamping components on the rebar cage clamping mechanism are precisely aligned with the preset clamping points on the rebar cage, and the rebar cage is firmly clamped by the clamping action of the clamping components. The traveling mechanism drives the entire clamping system to smoothly transport the rebar cage to directly above the preset pouring position, and then slowly lowers it to accurately place the rebar cage in the preset position.

[0063] The rebar cage clamping mechanism uses multiple clamping components to simultaneously hold the rebar cage, ensuring it remains horizontal during hoisting and avoiding the tilting problem that can easily occur with traditional single-point hoisting. Simultaneously, the smooth operation of the traveling mechanism effectively prevents swaying during transportation, protecting the stirrups and other structural elements on the rebar cage from displacement or damage.

[0064] S300: Concrete pouring operation is carried out at the preset pouring station to produce track slabs.

[0065] Specifically, in this step, the first step is to check whether the position of the reinforcing cage is accurate and whether the protective layer spacers are in place. During the concrete pouring process, an immersion vibrator is used to compact the concrete, ensuring it is fully dense. After pouring, a trowel is used to smooth the concrete surface, and geotextile is used for curing.

[0066] By adopting the above technical solution, the track slab casting construction method provided by this invention achieves precise clamping and stable transfer of the reinforcing cage through a reinforcing bar hoisting system. This effectively avoids problems such as tilting and swaying of the reinforcing cage during transfer, ensuring the integrity of the reinforcing cage and thus guaranteeing the forming quality and overall strength of the track slab. This method is simple to operate, highly efficient, and significantly improves the production quality and construction efficiency of track slabs.

[0067] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
